Because it IS a scalpel!
Doc sent me a couple of surgical scalpels to take a look at under the scope.
The eyeball test was pretty unimpressive. By looking at the glint along the edge, I could see that the flat part of the scalpel was a bit wavy, and didn't look to have a particularly keen edge.
Taking a pic under the scope was difficult as well, because apparently the egde has some sort of rounded/convex micro-bevel, and so it was difficult to get the correct lighting. Anyhow, you can see the result. The metal seems to have some sort of grain structure to it, embedded doo-dads (that's the kind of terminology you get to use after 4 years of med school...). The edge itslef looks fine enough, but you can see that it is a bit wavy and convexed. Not overly impressive, did not pass the HHT. Then again, these are designed to saw through tissue, not whisper through whiskers.
As a bit of synchronicity, I had a dermatology appointment yesterday to have a mole excised, and the doc there also used B-P scalpels. I can confirm that they do indeed slice and dice with the best of them.
With a liberal dose of lidacane!
